Hi.

If you use an external crystal *oscillator*, it will comply with the term
"external clock" which according to the errata *will* work.=20

The errata is also referring to the feature "Primary Oscillator Crystal".

It also says that rev A3 *does* work with a crystal and there is also
the normal crystal-with-two-caps circuit as an example for A3.

I would read it that you cannot use an external crystal oscillator as the
primary oscillator. In any event I would get out a breadboard and try the
internal oscillator with a crystal.
